# setenforce 0

In addition, you can run the command.

# setenforce Permissive

Any of these commands will temporarily disable SELinux until the next restart.

# vi / etc/selinux/config

Set the SELinux property to Disabled, as follows:

# This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:# enforcing-SELinux security policy is enforced.# permissive-SELinux prints warnings instead of enforcing.# disabled-No SELinux policy is loaded.SELINUX=disabled# SELINUXTYPE= can take one of these three values:# targeted-Targeted processes are protected,# minimum-Modification of targeted policy. Only selected processes are protected.# mls-Multi Level Security protection.SELINUXTYPE=targeted

Save and exit the configuration file, and then restart the CentOS 8 Linux system using any of the following commands.

# reboot# init 0# telinit 0

Now, use the command to check the status of SELinux.

[linuxidc@localhost www.linuxidc.com] $sestatusSELinux status: disabled
